Tiger Fire & Security Limited designed and specified the installation of a BS5839-1: 2002 compliant Category L5 addressable fire detection system. A Category L5 system is one in which the protected area(s) and/or the location of detectors is designed to satisfy a specific fire safety objective. Often the design is based on a fire risk assessment or forms part of a fire engineering solution.
Tiger Fire & Security Limited selected a system based around Hochiki's Enhanced Systems Protocol (ESP). ESP is a total communications solution for intelligent fire detection and fully integrated systems. It has a multi-purpose structure that provides the flexibility and expansion to accommodate simple addressable systems through to sophisticated integrated building management and safety systems.
Gareth comments,
‘Hochiki's proven reliability made it the obvious choice for this installation and I knew that it would act as a one stop shop for all the Stadium's fire detection needs. The ESP protocol is extremely robust and we've never experienced any issues or problems with it'.
The Stadium's West Stand has five levels with Hospitality Suites, Player / Changing areas, Media Rooms, Club Shops, and Chief Executive Suite, whilst the general concourse area is effectively an outside environment. In this area Tiger Fire & Security Limited used Hochiki's multi-sensors and addressable beacons to reduce the likelihood of unwanted alarms. The fire detection system was fully integrated with the PA/VA system and it operates in two modes – match day and non-match day, each specifically designed to ensure maximum safety at different times.
To get the scale of the installation into perspective, the fire detection system and PA/VA system used a combined total of 20km of cable and 350 Hochiki devices, including smoke detectors, multi-sensors, loop base sounders and beacons, and input/output units. These components are linked to four networked panels located around the stadium, with the master control panel located in the Stadium's match control room.
Hochiki's ALG-EN optical smoke sensors were also installed which feature the company's High Performance Chamber Technology. Hochiki's chamber design minimises the differences in sensitivity experienced in flaming and smouldering fires. The result is a high performance optical chamber that is equally responsive to all smoke types and helps to reduce the possibility of unwanted alarms.
